CHARLES O. BLACKWELL, OF HANNA, WEST VIRGINIA, ASSIGNOR OF ONE-HALF T0 JOHN B. YEAGER, 0F WALKER, WEST VIRGINIA.

CELLULAR PACKING STRUCTURE.

To all whom it may concern Be it known that 1, CHARLES 0. BLACK- wELL, a citizen of the United States, residing at Hanna, in the county of Wood and State of West Virginia, have invented certain new and useful Improvements in Cellular Packing Structures, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to egg cells or cases, and particularly that variety of egg cell or case which is composed of intersecting strip of pasteboard or like material, the strips being notched or slotted so as to have locked engagement with each other.

The general object of my invention is to provide an egg case of the above character which will be more durable and stronger than egg cases as ordinarily constructed and in which the strips will be more securely interlocked with each other so as to prevent the accidental detachment of the several strips.

A further object of my invention is to so form the case that it may be readily assembled and may be cheaply made.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of my cell structure in assembled position; Fi". 2 is a face view of one of the strips; Fig. 3 is a face view of the other strip.v

Referring to these figures. it will be seen that my improved egg case is composed of a series of parallel strips or slats 2 and a series of parallel strips or slats 3 normally intersecting the strips 2 at right angles. The strips 2 are formed with a plurality of pairs of notches or Slits 4 extendinginward from both side edges. the notches of each pair being in alinement. Each strip 8 has the longitudinally extending end slots 5 and the intermediate slot 6. The end slots 5 are each intersected by two slots 7 and 7 at right angles to the end slot. The slot 7'" is disposed inward of the eXtremitv of the slot 5, as shown clearlv in Fig. 2. The adiacent alls of the slots 7 and 7 at the intersection of these slots with the slot 5 a e cut awa as at S. The intermediate slot (3 at spaced in- Specification of Letters Patent.

tervals is intersected by slots 7 and 7 at right angles to the slot 6, the end slots 7 however, being disposed inward of the ends of the slots 6. As illustrated there are three slots 7 intersecting the slot 6. The inner walls of the end slots 7 are cut away, as at 8, and the wall of the middle slot 7 is also cut away as at 8. The purpose of cutting away the wall of the slots 7 and'7 as at 8 is to permit the strips 2 to be rotated within the slots 7 to bring these strips 2 into alinement with the slots 5 and (3 and thus permit the withdrawal of the strips 2 from the interlocked engagement with the strips 3. It will be seen that with this construction, when it is desired to assemble the strips 2 and 3, the strips 2 are threaded through the slots 5 and 6 of the strip 3 and then turned so as to dispose the necks between the notches 4 of the strips 3 within the slots 7 and 7 The necks 4* between the notches 4 of the strips 2 are slightly wider than the entrance into the slots 5 and 6 formed by the cut away portions 8, and as a consequence when the strips 2 are in place within the slots 7 and 7 the strips 2 will be held interlocked with the strips 3 and at right angles thereto, thus forming a cellular structure which may be folded fiat for transportation but which may be readily opened up for insertion in an egg crate to thereby form a series of egg compartments or cells. Because of the fact that the strips are interlocked with each other in the manner above described, they cannot readilv become detached, the cellular structure formed by the slats will be more substantial than with the ordinary construction, and ma be used a large number of times without damage.

Havina thus decribed my invention, what I claim is:

A cellular structure comprising two sets of intersecting strips, one set being provided with a plurality of uniformly spaced slits extending inward from its side cd' es. the other set being formed with a plurality of longitudinally extending slots having a length equal to the width of the first-named stri s and intersected b transversely extend ng slots having a len th equal to the s ace between the inner ends of each pair of slits on the first named set of strips, the wall of each intersecting slot being cut away at In testimony whereof I hereunto aflix my the inlters eotion of the slotfs whereby to persignature in the presence of two Witnesses. lnit tie irst-nalnec set 0 strip to be in- I q serted Within the longitudinally extending CHARLEb BLACKVVELL' slots and then rotated out of alinement with l/Vitnesses: v
